Description

Technical Field

[0001] The present invention relates to the technical field of car stopping technology, in particular to an emergency elevator car stopping device. Background Art

[0002] In today's elevator safety technology, the car brake system for emergency braking is a critical line of defense for ensuring passenger safety. Traditional car brake systems typically consist of a brake-stop trigger monitoring mechanism and an actuator. The brake-stop trigger monitoring mechanism often relies on various sensors to monitor the elevator's operating status in real time. Once an anomaly is detected, it sends a signal to the actuator, prompting it to activate and achieve the braking effect.

[0003] However, this type of existing technology has many drawbacks that are difficult to ignore. On the one hand, the special environment of the elevator shaft has a significant impact on the equipment. The temperature of the shaft wall fluctuates significantly with the change of seasons and the alternation of day and night. During the hot summer period, the temperature in the shaft is high, while in cold winter areas, the temperature is low. At the same time, the ventilation conditions in the shaft are poor, and dust is very easy to accumulate. These factors are a severe test for the electronic equipment that is closely linked within the mechanism. High temperatures will hinder the heat dissipation of electronic devices, accelerate component aging, and reduce their performance and reliability. Low temperatures will cause the physical properties of some electronic materials to change, affecting the normal operation of the circuit. The accumulation of dust will not only cause short circuits in electronic components, but also increase contact resistance, resulting in unstable signal transmission. In the above case, once any of the electronic components is damaged due to environmental factors, the signal transmission and control logic of the entire braking system will be disrupted, which will affect the overall braking work, resulting in braking delays or even failures, seriously endangering the lives of passengers.

[0004] On the other hand, the non-integrated design of the monitoring and actuator mechanisms also raises a series of issues. Since the two are independent, they need to be precisely positioned and debugged separately during installation, which undoubtedly greatly increases the difficulty and complexity of installation and requires a high level of professional skills and experience from the installer. Furthermore, the independent design increases the number of connecting lines between the two mechanisms, which not only complicates wiring but also makes signal transmission failures prone to aging and wear of the lines. Furthermore, the non-integrated design makes the overall system larger, occupying more space in the elevator shaft, which to some extent limits the size design and space utilization efficiency of the elevator car.

[0005] Therefore, the present invention proposes an emergency elevator car braking device to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose an emergency elevator car braking device to solve the problems existing in the prior art.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an emergency elevator car braking device, comprising: a car body, a crossbeam, a clamping member, and a guide rail, wherein the crossbeam is fixedly connected to the bottom end of the car body, the clamping member is symmetrically fixedly connected to both ends of the crossbeam, and the guide rail is arranged on both sides of the car body, and further comprising: a self-starting brake trigger mechanism, the self-starting brake trigger mechanism comprising a self-starting trigger assembly and a car brake assembly; mechanism A, mechanism B, and the superordinate writing of mechanism A and mechanism B;

[0008] The self-starting trigger component is used to quickly trigger when the car stalls, so as to maintain the stability and safety of the car;

[0009] The car brake assembly is used to perform emergency braking on the car body.

[0010] Preferably, the self-starting trigger assembly includes a support member A fixedly connected to the bottom of the clamping member, an auxiliary wheel is rotatably connected to the support member A, and a guide groove is provided on the auxiliary wheel.

[0011] Preferably, a support member B is fixedly connected to the inner side of the bottom of the clamping member, a guide bar is fixedly connected to the support member B, a sliding rod is slidably connected in the guide bar, and the end of the sliding rod away from the guide bar is slidably connected in the guide groove.

[0012] Preferably, a vertical push rod is fixedly connected to the sliding rod, and an air push plate is fixedly connected to the end of the vertical push rod away from the sliding rod. A column cavity tube is symmetrically fixedly connected to the support member B, and the air push plate is slidably connected in the column cavity tube. An electric-controlled air valve is fixedly connected to the side wall of the column cavity tube, and a one-way valve tube is fixedly connected to the top of the column cavity tube.

[0013] Preferably, the car brake assembly includes a supporting block fixedly connected to the middle of the clamping piece, the middle of the clamping piece is fixedly connected to a guide clamping piece, the supporting block is slidably connected to a brake block, and the brake block is provided with an oblique groove.

[0014] Preferably, a sliding column is fixedly connected to the back of the brake block, a lifting strip is vertically provided in the middle of the clamping part, an auxiliary block is symmetrically fixedly connected to the lifting strip, a transverse groove is opened through the auxiliary block, and the sliding column is slidably connected in the transverse groove.

[0015] Preferably, a hollow column is fixedly connected to the top of the clamping member, a disc is slidably connected inside the hollow column, and the top of the lifting strip is fixedly connected to the disc.

[0016] Compared with the prior art, the present invention provides an emergency elevator car braking device, which has the following beneficial effects:

[0017] 1. The present invention can bring the following benefits to elevator protection through overall design:

[0018] Enhanced braking reliability and additional power support: When the vehicle stalls, the auxiliary wheels are forced to rotate rapidly, indirectly providing braking power for the vehicle. This means that even if the braking system fails to respond in time due to power failure or other factors, the power generated by the auxiliary wheels can still drive the brake device. This increases the redundancy of the braking system, improves braking reliability, and reduces the risk of brake failure due to a single failure mode.

[0019] Stable braking force output: The rotation speed of the auxiliary wheel in a stalled state is related to the stall degree of the car body, and the auxiliary power can be adjusted in real time according to the actual situation. The faster the car body stalls, the greater the auxiliary power provided by the auxiliary wheel. This helps to achieve stable braking force output under different stall conditions, allowing the car body to stop more smoothly and reducing car shaking or tilting caused by unstable braking force.

[0020] Reduce the impact of environmental factors: The temperature and dust in the elevator shaft will affect the performance of the electronic equipment in the traditional braking system. However, the working principle of this component is relatively simple, does not rely on complex electronic equipment, and is less affected by environmental factors. Even in harsh shaft environments, it can work relatively stably, providing continuous auxiliary support for elevator braking, reducing the possibility of brake system failure due to environmental factors.

[0021] Optimize energy utilization: The kinetic energy of the car body during stall is converted into rotational energy of the auxiliary wheels, which is further used for braking. This energy recovery and reuse method optimizes the energy utilization efficiency during the elevator braking process. Compared with traditional braking systems that rely solely on friction to consume energy, this design can more fully utilize the kinetic energy of the car, reduce energy waste, and also reduce the burden on other components of the braking system.

[0022] 2. The overall design of the self-starting and braking integrated mechanism of the present invention has the following advantages:

[0023] Instant response and efficient braking: When the car stalls, the auxiliary wheels can immediately sense it and cooperate with the guide groove to provide the necessary braking air to the car brake assembly, achieving rapid response. This is much faster than traditional braking systems that rely on electronic signal transmission and complex control logic to initiate braking. It can significantly shorten the braking reaction time and effectively reduce uncontrolled displacement of the car in emergency situations, reducing the risk of accidents.

[0024] Enhanced safety and reliability, with autonomous emergency response: This design has autonomous runaway self-start and self-stop functions, and does not rely on external complex control systems or power supply. In the event of an emergency when the elevator control system fails, it can still provide reliable braking protection for the elevator, increasing the redundancy and reliability of the elevator safety system.

[0025] 3. The present invention provides the following benefits by arranging the electric control air valve near one end of the guide rail and utilizing the design of cleaning the guide rail:

[0026] Optimize the braking environment and reduce braking interference: Blowing the guide rails through the electric valve port can promptly remove dust and debris on the guide rails, preventing these external factors from affecting the braking effect of the subsequent brake pads and guide rails. This reduces the interference of additional friction and jamming caused by unclean guide rails during braking, making the braking process smoother and more reliable.

[0027] Extend component life: Keeping the guide rails clean can reduce wear between brake components and the guide rails, such as the contact surface between the training wheels and the guide rails, reduce wear and scratches caused by dust particles, help extend the service life of the training wheels and brake pads in contact with the guide rails, and reduce maintenance costs and replacement frequency;

[0028] Ensure braking stability and consistent inflation volume: Ensure that the auxiliary wheels in the opposite braking equipment rotate at a consistent speed on the clean guide rails, which can effectively ensure the consistency of the inflation volume indirectly supplied to the braking working condition; stable inflation volume can make the braking system produce uniform and stable braking force during the braking process, avoiding the problem of inconsistent braking time of the opposite braking equipment on the car body due to uneven braking force, thereby making the braking appear at a larger tilt angle, improving the stability and safety of the car when braking.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0045] Example

[0046] Please refer to Figures 1 to 3 、 Figure 5 、 Figure 6 、 Figure 9 As shown:

[0047] To solve the problems mentioned in the technical solution, the embodiment of the present application provides an emergency elevator car stopping device, comprising: a car body 1, a crossbeam 2, a clamping member 3, and a guide rail 4, wherein the crossbeam 2 is fixedly connected to the bottom end of the car body 1, the clamping members 3 are symmetrically fixedly connected to both ends of the crossbeam 2, and the guide rails 4 are arranged on both sides of the car body 1, and further comprising: a self-starting brake trigger mechanism, which includes a self-starting trigger component 5 and a car brake component 6;

[0048] The self-starting trigger component 5 is used to quickly trigger when the car body 1 stalls, so as to maintain the stability and safety of the car body 1;

[0049] The self-starting trigger assembly 5 includes a support member A501 fixedly connected to the bottom of the clamping member 3, and an auxiliary wheel 502 is rotatably connected to the support member A501, and a guide groove 503 is provided on the auxiliary wheel 502. A support member B504 is fixedly connected to the inner side of the bottom of the clamping member 3, and a guide bar 505 is fixedly connected to the support member B504. A sliding rod 506 is slidably connected in the guide bar 505, and the end of the sliding rod 506 away from the guide bar 505 is slidably connected in the guide groove 503, a vertical push rod 507 is fixedly connected to the sliding rod 506, and the end of the vertical push rod 507 away from the sliding rod 506 is fixedly connected to the push piece 508, a column cavity 509 is symmetrically fixedly connected to the support member B504, and the push piece 508 is slidably connected in the column cavity 509, an electric-controlled air valve 510 is fixedly connected to the side wall of the column cavity 509, and a one-way valve tube 511 is fixedly connected to the top of the column cavity 509.

[0050] in:

[0051] The integrated self-starting braking mechanism can perform self-starting braking when the car stalls, ensuring the safety of people in the car.

[0052] The self-starting trigger component 5 is used to quickly trigger when the car body 1 stalls, thereby maintaining the stability and safety of the car body 1.

[0053] There is an electrical connection between the speed sensor installed on the car body 1 and the electronically controlled air valve 510. When the speed sensor on the car body 1 detects that the car body 1 is in a stalled state, the electronically controlled air valve 510 can be controlled by the main controller to close quickly.

[0054] When the electric-controlled air valve 510 is closed, the air pushing piece 508 in the column cavity 509 will push the gas into the hollow column 609 through the one-way valve tube 511. When the electric-controlled air valve 510 is not closed, the gas pushed by the air pushing piece 508 will be blown to the guide rail 4 through it, so as to be used for cleaning and maintenance of the guide rail 4.

[0055] The one-way valve tube 511 passes through the clamping member 3 , and the other end is connected to the hollow column 609 .

[0056] Further examples: Please refer to Figures 2 to 4 、 Figures 7 to 9 As shown:

[0057] The car brake assembly 6 is used to perform emergency braking on the car body 1. The car brake assembly 6 includes a supporting block 601 fixedly connected to the middle of the clamping part 3, a guide clamp 602 fixedly connected to the middle of the clamping part 3, a brake block 603 slidably connected to the supporting block 601, an oblique groove 604 is provided on the brake block 603, a sliding column 605 is fixedly connected to the back of the brake block 603, a lifting bar 606 is vertically provided in the middle of the clamping part 3, an auxiliary block 607 is symmetrically fixedly connected to the lifting bar 606, a transverse groove 608 is provided on the auxiliary block 607, the sliding column 605 is slidably connected in the transverse groove 608, a hollow column 609 is fixedly connected to the top of the clamping part 3, a disc 610 is slidably connected in the hollow column 609, and the top of the lifting bar 606 is fixedly connected to the disc 610.

[0058] in:

[0059] The car brake assembly 6 is used to perform emergency braking on the car body 1 .

[0060] The brake block 603 can slide laterally on the supporting block 601 .

[0061] The oblique groove 604 is slidably fitted with the guide clamp 602 .

[0062] The sliding post 605 is slidably fitted into the transverse groove 608 .

[0063] The disc 610 fits snugly within the inner cavity of the hollow column 609 and can slide stably even in a sealed state.

[0064] Everything in the above example works as follows:

[0065] The following is the working process of the self-start trigger component 5:

[0066] Under normal circumstances, the car body 1 will be normally raised and lowered on the guide rail 4 with the assistance of the cross beam 2 and the clamping member 3. When the elevator is out of control, the guide rail 4 will move quickly on the guide rail 4 with the connected clamping member 3. At this time, the auxiliary wheel 502 provided on the clamping member 3 will move quickly in close contact with the guide rail 4. In this process, the sliding rod 506 in the guide bar 505 will move up and down vertically under the dual restrictions of the sliding rod 506 and the guide groove 503 provided on the auxiliary wheel 502. In this action, the sliding rod 506 will move in the column cavity 509 with the assistance of the vertical push rod 507. There is an electrical connection between the sensor and the electric-controlled air valve 510. When the speed sensor on the car body 1 detects that the car body 1 is in a stalled state, the electric-controlled air valve 510 can be quickly closed by the main controller; and when the electric-controlled air valve 510 is closed, the air-pushing piece 508 in the column cavity 509 will push the gas into the hollow column 609 through the one-way valve tube 511. When the electric-controlled air valve 510 is not closed, the gas pushed by the air-pushing piece 508 will be blown to the guide rail 4 through it, so as to be used for cleaning and maintenance of the guide rail 4; at this time, when the electric-controlled air valve 510 is closed, the air-pushing piece 508 will push the air in the column cavity 509 into the hollow column 609 through the one-way valve tube 511, so as to provide brake gas delivery for the car brake assembly 6;

[0067] Please refer to the above working process Figures 1 to 3 、 Figure 5 、 Figure 6 、 Figure 9 .

[0068] The following is the working process of the car brake assembly 6:

[0069] Furthermore, as the one-way valve tube 511 delivers gas into the hollow column 609, the disc 610 in the hollow column 609 will move upward from the bottom end in the hollow column 609. During this movement, the disc 610 will move the lifting bar 606 upward. Furthermore, during the upward movement of the lifting bar 606, the lifting bar 606 will promote the movement of the brake block 603 through the cooperation between the transverse groove 608 on the fixed auxiliary block 607 and the hollow column 609 on the brake block 603. It should be noted that in this movement, the guide clamp 602 and the oblique groove 604 on the brake block 603 provide guiding assistance, so that the brake block 603 can move laterally on the supporting block 601 gradually approaching the guide rail 4, thereby performing the stall braking operation of the car body 1.

[0070] Please refer to the above working process Figures 2 to 4 、 Figures 7 to 9 .

[0071] Furthermore, the overall design of the self-activating brake integrated mechanism, which has the features of self-activation in the event of loss of control and self-stopping of all components of the mechanism after braking, can provide the following benefits: instant response and efficient braking. When the car body 1 stalls, the auxiliary wheel 502 can immediately sense it and, through cooperation with the guide groove 503, provide the necessary braking air to the car brake assembly 6, achieving rapid response. This is much faster than traditional braking systems that rely on electronic signal transmission and complex control logic to initiate braking, and can significantly shorten braking reaction time. In emergency situations, it can effectively reduce uncontrolled displacement of the car and reduce the risk of accidents.

[0072] Enhanced safety and reliability, with autonomous emergency response: This design has autonomous runaway self-start and self-stop functions, and does not rely on external complex control systems or power supply. In the event of an emergency when the elevator control system fails, it can still provide reliable braking protection for the elevator, increasing the redundancy and reliability of the elevator safety system.

[0073] Furthermore, by arranging the electric-controlled air valve 510 near one end of the guide rail 4 and utilizing the design of cleaning the guide rail 4, the following benefits can be achieved: the braking environment is optimized and braking interference is reduced; by cleaning the guide rail 4 through the air port of the electric valve, dust and debris on the guide rail 4 can be removed in a timely manner, preventing these external factors from affecting the subsequent braking effect of the brake block 603 and the guide rail 4, thereby reducing the interference of additional friction and jamming caused by the unclean guide rail 4 during braking, making the braking process smoother and more reliable;

[0074] Extending component life: Keeping the guide rail 4 clean can reduce wear between brake components and the guide rail 4, such as the contact surface between the auxiliary wheel 502 and the guide rail 4, reducing wear and scratches caused by dust particles, helping to extend the service life of the auxiliary wheel 502 and the brake pad 603 in contact with the guide rail 4, reducing maintenance costs and replacement frequency;

[0075] Ensure braking stability and ensure consistent inflation volume: Ensure that the auxiliary wheel 502 in the oppositely arranged brake device rotates at a consistent speed on the clean guide rail 4, which can effectively ensure the consistency of the inflation volume indirectly supplied to the braking working condition; the stable inflation volume can make the braking system produce uniform and stable braking force during the braking process, avoiding the problem of inconsistent braking time of the oppositely arranged brake device on the car body 1 due to uneven braking force, thereby making the brake appear at a larger tilt angle, thereby improving the stability and safety of the car when braking.

[0076] Furthermore, the overall design offers the following benefits for elevator protection: enhanced braking reliability and additional power support. When car 1 stalls, the auxiliary wheel 502 is forced to rotate rapidly, indirectly providing braking power for car 1. This means that even if the braking system experiences delayed feedback due to a power failure or other factors, the power generated by the auxiliary wheel 502 can still activate the brakes, increasing the redundancy of the braking system, improving braking reliability, and reducing the risk of brake failure due to a single failure mode.

[0077] Stable braking force output: The rotation speed of the auxiliary wheel 502 in a stalled state is related to the stall degree of the car 1, and the auxiliary power can be adjusted in real time according to the actual situation. The faster the car 1 stalls, the greater the auxiliary power provided by the auxiliary wheel 502. This helps to achieve stable braking force output under different stall conditions, allowing the car 1 to stop more smoothly and reducing car shaking or tilting caused by unstable braking force.

[0078] Reduce the impact of environmental factors: The temperature and dust in the elevator shaft will affect the performance of the electronic equipment in the traditional braking system. However, the working principle of this component is relatively simple, does not rely on complex electronic equipment, and is less affected by environmental factors. Even in harsh shaft environments, it can work relatively stably, providing continuous auxiliary support for elevator braking, reducing the possibility of brake system failure due to environmental factors.

[0079] Optimized energy utilization: The kinetic energy of the car body 1 when it stalls is converted into rotational energy of the auxiliary wheel 502, which is further used for braking. This energy recovery and reuse method optimizes the energy utilization efficiency during the elevator braking process. Compared with traditional braking systems that rely solely on friction to consume energy, this design can more fully utilize the kinetic energy of the car, reduce energy waste, and also reduce the burden on other components of the braking system.
